[Rcode427]

I have a few transmissions and looking for a certain one I have . I am near sure I found it but need a site to check the tag to be sure . I know there is a site that has all codes because I used to have it , forgot now . I have the 4 speeds , need autos . The numbers on the tag are (PJCB---11854)..I think it is a 429 COBRA JET tranny . Can someone help ????
